Steel Reusable 1 Wire Braid Reduced Bore Two-Piece Fitting, 3/4-16 Female JIC 37 deg Flare Swivel, -06 Hose, Straight

Reduced bore means the internal passage is sized down from what a full-bore -06 fitting would carry. The hose end connects to -06 hose, but the bore through the fitting itself is narrower. For most low-to-moderate flow applications that's not an issue, but if you're running high flow rates or have tight pressure drop tolerances in your circuit, it's worth accounting for that restriction when you size things out.

You’re looking at a straight, two-piece reusable steel fitting made for -06 hose, with a 3/4-16 female JIC 37 degree flare swivel on the threaded end.

This fitting is designed for use with a -06 hose size, according to the product details.

No mandrel is needed for assembly on this one. The reusable design lets you install it without that extra tooling, which saves a step and keeps things straightforward on the shop floor. Just make sure you're working with a -06 hose, since that's what the fitting is sized for on the hose end.
